reedal Posted July 26, 2015 Report Share Posted July 26, 2015 Between my batteries I fuse for the amount of current my wire can handle at 20ft, even though it's a 10ft run at best. You don't have to fuse for the wire if you current draw won't be that high, but make sure you don't fuse any higher than that.

reedal Posted July 26, 2015 Report Share Posted July 26, 2015 What wire are you using? Size/brand? OFC or CCA? How much current does your alternator put out at max? And what size fuses do your amps require SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...

reedal Posted July 26, 2015 Report Share Posted July 26, 2015 Quick google search says that wire is good to 300A, but I wouldn't fuse higher than what your amps need (230A). Don't know about the quality of that wire either SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
